- HOUSING FOR MECHANIGAL MOVEMENTS AND FASTENINGS THEREOF.

To all whom it ma "concern:

Be it known ti'at I, HERMAN G. PAPE,

of New York, in the county and State of New York have invented a new anduseful Housing for Mechanical Movements and Fastenings Thereof, of whichthe following is a specification.

Heretofore in housings; for mechanical movements which consisted of a'plurality of parts, said parts were held together'by fastening meanswhich included a screw or other locking appliance extending through thehousing, which screw often became alive when the mech'anical movementwas connected to electric wires because, among other things,a strand ofthe cord connected to the mechanical movement would touch the screw andgive a severe shock toa person standmg might even be killed.

The main object of overcomethese and other defects and a feature of myinvention consistsin completely surrounding the mechanical movement withcompletely insulated portions.

Another feature consists in having the ,means which holdthe parts of thehousing together insulated at all points from the mechanical movementand the wires, if the latter are used. Inthe preferred form of suchmeans Iuse .a split ring which-is not only easily put on and taken offbut is com pletely insulated at all times, so. that the user feels sureat all times that he will not receive a shock, and this is-a veryimportant advantage.

Another feature of my. invention is pro- VlSlOIl for ready removal ofthefastening means WhICh feature is-not only of great -.utility in itselfbut-- adds to the feeling of i security in handling'the device becauseof ment.

pletely insulated. F Another feature of my invention is tha theiknowledge that that fastening is comthere is no danger of the fasteningslipping Another feature is a housing consisting of a plurality ofparts, which parts have interlockingportions to prevent relative movemy.inventionv is tot- I y cylindrical Shell made with an interiorSpecification of Letters Patent.

Other features will be pointed out below. In the drawings, f Figure 1 is-a central longitudinal .sec-' tional view of a device embodying myinvention; V

Fig. 2 is a section on line 22 of Fig. 1, showing the outer housingalone;

a Fig. 3 is a side elevation of the switch shown iii-Figs. l-and 2;

Fig.4 is a section on line 44 of Fig. 3 withthe interior partof theframe removed;

Fig. 5 illustrates a modification;

Fig. 6 is a section on line 6-6 of Fig. 5'; and a Fig. 7 illustrates amodification described below. p

My housing is longitudinally divided and is made up of two hollowsections 1 and 2 of. poroelaln or other suitable material and aninterior part or section 3 that is inclosed and interlocked with thehousing sections land 2. Each section 1 and 2 isa substanannular recess4, the two semi-circularre; cesses 4 making up' a pocket into which theinterior section 3-fits snugly. Section 3 is substantially cylindricalin form and recessed at its ends to accommodate the parts of the switchmechanism and provide a partition 5 on which said parts are mounted.Upon its exterior'the longitudinally divided housin G'and within' one ofwhich is arranged a split spring ring8, Figs. I ahd ;5, which serves tohold the two sections together. Ring 8 is formed upon itsinner side andnear its middle with a boss 9 fitting into a hole 10 provided in section1, the engagement of boss 9 with hole 10 serving to' hold the split 11of ring 8 away from the joints between the sections 1 and 2.

1n order to hold the two sections 1 and 2 against relative movementlongitudinally the section 1 is made at each side about midway of itslength with an integral'projection 12 is made with two annular grooves.1

posts 17 and 18 to wires 19 and; 20, the entrance of which is permittedby the opening 21 formed in sections 1 and 2.

In Figs. 5 and 6 I show a modificationin which the split ring 81 has itstwo ends hooked inwardly to enter and engage recess 22 to preventrotation of the split ring. Ad-

I j acent to the ends of the ring and at one side thereof member'2 isformed with a beveled depression 23 appearing in Fig. 5 and dotted inFig. 6, the-function of this depression being to permit the insertion ofa suitable tool such as a screw driver beneath an end portion of thesplit ring so that the latter may be readily and quickly removed andthis is an important feature also for the reason that the user will feelassured that,

- onaccount of the complete insulation of the ring, he will not get ashock.

In Fig. 7 I show the two sections 1 and 2 the plane of division beingcrosswise of the device, section .1 having a projection 24:.

of the spring engaging the cooperating recess locate. the ends of thespring so that they will not be opposite the joints between the sections1 and 2.

'What ll claim is:

1. A housing for a mechanical movement I comprising a plurality. ofparts; and an interior separable portion interlocked with said parts ofthe housing and adapted to support a mechanical movement.

2. A housing for a mechanical movementcomprising a plurality of parts,one of which has a recess and a split ring having its ends engaging saidrecess to prevent rotation of said ring.

3. A housing'for a mechanical movement comprising a plurality of parts;and a split ring to hold said parts together, one of said parts having adepression at one side of, but adjacent to, one end of said spring topermit ready removal of the latter.

4. A housing forl a mechanical'movement comprising a plurality ofinterlocking parts susceptible of relative sidewise movement;

an interior separable portion pocketed and supported by said parts andadapted to sup.-

1 port a. mechanical movement; and means to hold said parts together. g

5.1 A housing for a mechanical movement comprising a plurality ofinterlocking parts;

- bers in 'positlon.

comprising an outer housing divided longitudinally into two partssusceptible of relative sidewise movement, and an interior separableportion on which the mechanical movement is mounted, said interiorportion being interlocked with the two parts of the housing so that itisheld against movement relatively thereto; means for holdin the two partsof the housing'against re ative longitudinal displacement; and means forfastening the two parts of the housing together against sidewisemovement.

8. A housing for a mechanical movement comprising a plurality of partssusceptible of relative movement in a sidewise direction and in alongitudinal direction; means to holdsaid parts against relativemovement in one of said directions; and an interior portion held inposition by said parts and itself holding said parts against relativemovement in the other of said directions.

9. A housing for a mechanical movement, comprising a support; amechanical movement mounted on said support; a plurality of housingmembers for said support and said movement; and a split ring to holdsaidmembers in proper relation to saidsupport. 10. A housing for amechanical movement :comprising a support; a mechanical move mentmounted on said support; a plurality of housing members for said supportand for said movement, said members and said support being formed toprevent relative movement between said members and said support; and asplit ring to holdsaid mem- 11. A housing for a mechanical movement.comprising asupport; a mechanical movement mounted on said support; aplurality of housing members for said support and for said movement,said members being grooved exteriorly and said members and said supportbeing formed to prevent relative movement between said members and saidsupport; and a split ring in said grooved exterior 'to position.
